Re: Water flow sensors?

["Tim Hawes" <timsyahoo@xxxxxxxxxxxxxx>]

Paul,

You could probably do this with a number of =A310 cylinder thermostats
clamped to the pipe, *but* I'm not sure whether they'd be responsive
enough if you're using plastic instead of copper. I guess you could
fit a copper section into your piping and mount the thermostats on
those and if you're adding sensing capability near the showers, that
pipework may be in copper anyway...

Although mains-rated, the simple thermostats are dry-contacts anyway.

HTH,

Tim.
